Embodiment 1

[0022] A third joint 21 is provided at the front end of the second connecting seat 2. The third joint 21 is a threaded joint. The third joint 21 communicates with the first connecting seat 1 to keep the stable use of the joint. Connecting holes 22 are opened at the end, and several locking holes 2 are opened on the left and right sides of the second connecting seat 2. When used as a three-way combination joint, the two connecting holes 22 are sleeved into the first connecting seat 1, so that The locking hole 23 corresponds to the position of the blind hole 13 of the first connecting seat 1, and the first connecting seat 1 is kept perpendicular to the second connecting seat 2, and then the bolt 24 is inserted into the locking hole 23 and the blind hole 13 to fix the second connecting seat. 2 seats are enough.

Embodiment 2

[0024] Since the third joint 21 communicates with the first connection seat 1, a fixing hole 4 is provided at the joint between the third joint 21 and the first connection seat 1. When using it as a straight-through joint, the second connection seat 2 needs to be disassembled and removed. The fixing hole 4 is closed to keep the tightness of the joint. A step 41 is set in the fixing hole 4 to delay the leakage of the medium, and then a tightening nut 14 is set on the first connecting seat 1, and the tightening nut 14 is placed on the fixing hole 4 , by arranging the elastic gasket 141 and the sealing gasket 142 on the tightening nut 14, the tightness of the connection between the tightening nut 14 and the fixing hole 4 is increased.

Abstract

The invention provides a three-way assembly variable joint comprising a first connecting base and a second connecting base. The first connecting base is vertical to the second connecting base, and the upper end of the first connecting base is provided with a first joint; the lower end of the first connecting base is provided with a second joint, and the front end of the second connecting base is provided with a third joint inward; the first connecting base, the first joint and the second joint are arranged coaxially, and the first connecting base, the first joint, the second joint and the third joint are connected to form through holes; the first joint is a welded joint, and the second joint is a hose joint; and the second joint is externally provided with a threaded part and an optical axis part, and the third joint is a pipe joint, and internally provided with threads arranged compactly. According to the three-way assembly variable joint provided by the invention, three joints of different types are integrated, and at the same time the three joints can also be changed to straight joints for use; and the three-way assembly variable joint can be applied to connecting a plurality of complex pipes, and the practicability is high.

Description

【Technical field】 [0001] The invention relates to the technical field of pipe joints, in particular to a variable joint of a tee combination. 【Background technique】 [0002] A joint is a connection tool between pipes and a detachable connection point between components and pipes. It plays an indispensable and important role in pipe fittings. At present, the joints on the market mainly include double joints, elbows, tees, crosses, etc., generally including a joint body. The internal tooth joint has a simple structure and a single connection form. The joint with this structure can no longer meet the needs of complex pipeline connections in the market. 【Content of invention】 [0003] The purpose of this invention is to solve the problems in the prior art, and propose a variable joint of three-way combination, which integrates three different types of joints, and at the same time, the three joints can also be used as straight-through joints, which can adapt to many A comple...
